This paper mainly based on the new processes of ozone-floating filter and ozone floatation which were tested in the water from the Queshan Reservoir. The process of ozone floating filter stated that little influence ccurred when the raw water was pre-treated by the ozone. UV254(Ultraviolet Rays)was removed in large amount (76.47%) if the ozone oxidation had been adopted. The removal rate could achieve...
One of China largest river, Songhua River was polluted due to the explosion at a PetroChina factory in Jilin province in 2005. A full scale test was carried out to investigate the removal of nitrobenzene in the raw water from polluted Songhua River. The removal and control effects of nitrobenzene by using Powered Activated Carbon (PAC) absorption and Granular Activated Carbon (GAC) filtration as emergent...
The effect of preoxidation Yellow River with light polluted water by composite potassium permanganate process are studied in the text. The best adding quantity of composite potassium permanganate is 1.5-3.0 mg/l, PAC as the flocculant, the best adding quantity is 60 mg/l. Under these conditions, pretreat Yellow River with mic-polluted water which the results show that permanganate preoxidation obviously...
The effectiveness of enhanced pollutants removal of pre-oxidation process with potassium permanganate composites (PPC) was studied in laboratory scale and full-scale, with polluted raw water of the navigation channel of the Pearl River and the West River respectively. The results from the jar tests demonstrate that PPC has an enhanced effect on coagulation, filtration and organic matters removal for...
